It bases on the fact that there is a booming market for exotic hotel vacations. It ranges from Ice hotels, to tree hotels, and there is even a underwater hotel in use as we speak. Jules Underwater Lodge in Florida. There has been big intents of underwater mega hotels in dubai and fiji that folded due problems on the finance front. So it seems logical to start with a single room or a underwater cabin-pod on a low scale and take it from there.

Submarine Sauna

Floating saunas are already a common sight on the lakes of Scandinavia but Swedish company Nordic Marine Living has created a sauna which allows guests to bathe in steam whist watching the fishes glide by. The ingenious invention has a floating platform with a hut on top, and a sauna capsule below. Power floodlights illuminate the depths allowing a most dreamlike sauna experience.

Escape pod "capsule hotel"

Your own survival pod! Escape pod hotel in a city centre dock location. Moored in The Hague, your room is a bright orange survival pod which once saw service on an oil rig platform. Originally built in 1972 they are 4.25 metres in diameter and unaltered apart from the addition of a lock on the outside and an ‘emergency' chemical toilet inside. While not everyone's luxury choice, each pod provides cosy protection from the elements for up to three occupants.

First created for accommodation as an art project in 2004, owner Denis Oudendijk has 8 different models ready for use and is currently working on additional locations in central Amsterdam and Nantes, France.

Part submarine, part research vessel, the 'SeaOrbiter' is currently on view at a Korean expo

It could be an alien spacecraft or a 21st century version of Captain Nemo's Nautilus from Jules Verne "20,000 Leagues Under the Sea," but in fact it's a live-aboard, ocean-going laboratory that could be exploring the seas as soon as late next year, says CNN in a recent news report.

Called the SeaOrbiter , the research vessel is the concept of French architect Jacques Rougerie. Currently the centerpiece of France's pavilion at Expo 2012 in Yeosu, South Korea, it has spent almost 12 years floating around as a mere concept. It recently completed its industrial design phase and construction is slated for October this year.

"All technical issues are resolved, all the modeling is done," says Ariel Fuchs, education and media director of the SeaOrbiter project. "We gathered institutional and industrial support five or six years ago and it's been a real institutional and financial project for the last two years."

It is expected to cost around $43 million and when built, will be 58-meters in height, taller than Nelson's Column, a monument in London. When launched, around 50% of the vessel will be below the water line, allowing for constant underwater study, Fuchs says.

"One of the first users will be the science community," he says. "It's designed to explore the ocean in a new way, mainly spending time under the sea, giving people the opportunity to live under the sea for a very long time, to observe, to undertake research missions, like marine biology, oceanography and climate issues."

At an estimated $30,000 per week, they don’t expect you to dive. Jump into an elevator and go 40 feet down to a corridor in order to access your underwater pod.There are also plans in the works for a 7-star under-water hotel in Dubai, for a mere $28,000 per night.
